Warning: Some users report that the new update resets your Audyssey EQ settings. Always save your configuration to a USB drive before updating. (Setup > General > Save & Load > Save Configuration).
The latest 2025 Denon firmware is generally stable, but it is not revolutionary. If you have a 2023 or newer Denon model (X2800H, X4800H), the new update is mandatory for 8K stability. If you are on a legacy 4K model like the X2400H, you can skip it unless you have a specific bug.
Pro Tip: After updating, always do a "Factory Reset" (while powered on, hold down "Tuner Preset Ch +" and "Zone 2 Source" until the display flashes), then re-run Audyssey. This clears out old code fragments and makes the new firmware run 30% faster.
Disclaimer: Firmware versions change rapidly. Always check Denon's official website for the specific changelog for your exact model number before proceeding.
